CYL'INDRICAL SHEET-METAL PACKAGE.

SPECIFICATION forming part .of Letters Patent No. 539,348, dated May14,1895.

' Application filed October 26, 1894. Serial No. 527,037. (No model.)

To all whom it may concern:

Be it known that I, FRANK G. CALDWELL, a citizen of the United States,residing at Wheeling, in the county of Ohio and State of West Virginia,have invented new and useful Improvements in Cylindrical Sheet- MetalPackages, of which the following is a specification.

This invention relates to sheet-metal roofingpackages, wherein plates ofmetal are convoluted or rolled into cylindrical form, and are designedto contain within them the fixtures, such as caps, cleats, and toolsnecessaryA to apply the plates to roofs. Y

The objects of my present invention are to provide novel, simple,efficient, and economical supporting heads on which the roofing platesare rolled, the construction being such as to facilitate handling thepackages; to provide novel means for binding the convolutions of therolled plates to the supporting heads for the purpose of retaining thepackage in proper cylindrical form and to provide a new and improvedconstruction of supporting heads whereby the roofing plates can beevenly and smoothly rolled into cylindrical packages while affordingconvenient means for grasping the ends of thepackages in handling thesame.

The invention consists in acylindrical package of convolved rootingmetal having supporting heads within its ends, each of which is composedof an annulus or hoop and crossed wooden strips secured at the ends tothe inside of the annulus or hoop, and stripsconvolved with the roofingmetal, extending parallel with the axis of the package, projecting fromthe ends thereof and fastened' to said crossed strips.

The invention is illustrated by the accompanying drawings, in which-Figure l is a perspective view of a cylindrical sheet-metalrooingpackage constructed according to my invention. Fig. 2 is a longitudinalcentral sectional. view of the same. Fig. 3 is a detail perspective view0f one of the supporting-heads; and Fig. 4 is a sectional view of asupporting-head,showing a modification of the invention.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein-'- The numeral l indicates a sheet metalroofing-plate, and 2 an annulus or hoop preferably composed of Wood, andprovided with two crossed' wooden strips 3 and- 4, mortised togethercentrally between their ends and secured at their extremities totheinside of the annulus or hoop by nails or other suitable fasteningdevices.

The sheet-metal rooting plate is designed to be convoluted or rolledinto the form of a hollow cylinder, so that it may contain within itscentral chamber the ixtures, such as caps,

cleats, and tools required to apply the roofing plate to a roof.

According to one' method of producing th cylindrical package, thecrossed Wooden strips of two hoops are engaged with suitable rotatingdevices, so thatthe hoops are rotated. The sheet-metal rooting is nailedto the two hoops, andthe rotation of the latter winds the metal plateinto cylindrical form. During the rolling Aor winding of the plate intocylindrical form, I introduce at intervals thin metal strips 5, whichareonvolved with the metal rootingplate, so that when the roofing-platehas been wound into a cylinder, the end portions of the metal strips 5project from the ends of the package and are susceptible of being bentdown upon and nailed, or otherwise fastened, to the crossed woodenstrips 3 and 4 of the hoops 2.` The inserted metal strips 5, whenapplied and fastened in the manner explained, serve to retain thegreater portions of the convolutions of the rooting plate in properform, and materially contribute to the production of a cylindricalpackage which can be handled or manipulated without liability ofbecoming broken apart or disarranged. After the sheet-metalroofing-plate has been convoluted or rolled into cylindrical form, awire 6 is tied around the periphery of the cylindrical package, for thepurpose of retaining the free end of the roofing plate in properposition.

While I prefer to provide a wire or wires, as at 6, to secure the freeend of the roofingplate, I- may employ some other contrivance to securethe same result.

It is possible to wind the sheet-metal roofing-plate into cylindricalform, and subsequently insert the hoops 2 with their crossed strips 3and Itinto the ends of the cylindrical package. If this method isadopted I prefer to construct the hoops With beveled or inclinedperipheries, as at 7, Fig. 4, to facilitate driving the hoops into thehollow end portions of the convoluted or rolled rooting-plate. I prefer,however, to employ the method first explained, wherein the supportingheads, composed of the hoops 2 and crossed strips 3 and 4, are engagedwith rotary devices for the purpose of rolling or winding thesheet-metal roong-plate into cylindrical form.

The improved construction of supporting head, composed of an annulus orhoop and crossed wooden strips, provides a self-bracing structure whichis very desirable and efficient, and serves to properly support the endsof the cylindrical package, and to retain within the center thereof thefixtures requisite to apply the roofing plates to roofs. The annulus orhoop also serves as a foundation for evenly and uniformly rolling orwinding the sheetmetal roofing-plate into the form of a cylinder Whilethe crossed strips brace the annulus or hoop, and are so relativelydisposed as to admit between them the fingers or hands, for thc purposeof handling or manipulating the package.

In the drawings the strips 5 are shown as short independent pieces, andin practice each one is about four inches in length and about one inchin width. The strips are held sutliciently tight by the winding of theroofing plate into a roll to accomplish the purpose of retaining thesupporting heads in position and holding the greater portions of theconvolutions of the rooting plate in proper form. The independent shortstrips 5 are more economical than if each strip extended the full lengthof the cylindrical package and projected from each end thereof.

Having 'thus described my invention, what I claim'is- A cylindricalpackage of convolved roofing metal having supporting heads within itsends, each of which is composed of an annulns or hoop and crossed woodenstrips secured at the ends to the inside of the annulus or hoop, andstrips convolved with the roofing metal, extending parallel with theaxis of t'ne package, projecting from the ends of the package andfastened to the said crossed strips, substantially as described.

In testimony whereof I have hereunto set 'my hand and afxed my seal inpresence of two subscribing Witnesses.
